### Importing a Direct CAD File

Direct CAD Interfaces (DCI) allow you to connect directly to your CAD software. As the CAD file is updated in your CAD software, the corresponding changes are reflected in PC-DMIS.

Instead of translating CAD data into the internal CAD format of PC-DMIS, the Direct CAD file types are accessed directly. That is, the CAD data of these file types remains in its native format after being imported. Routines native to the CAD type are used for all calculations done on the CAD data. Accessing the CAD data directly eliminates problems that can occur because of translation inaccuracies or limitations.

PC-DMIS supports the use of the following DCIs:

- CATIA 5

- Creo (previously Pro/Engineer)

- Solidworks

- NX (previously Unigraphics)

When you select the NX option, the NX file name appears in the Layers to Import dialog box.

For detailed information on importing Direct CAD files, see the "Direct CAD Interfaces" documentation.
